Nice bump. I had read this thread a long time ago before I did any levering, and now I'm starting to do levering and had a bunch of questions that this thread answered. I use a sleeve from an olympic bar and add weights at the end. I'm not sure if that was mentioned in this thread, but it works out great.
So is that like levering with a fat bar then? I'm having a little trouble picturing that working well.
I use an old standard size adjustable dumbbell handle. I put the weight on one end and on the other side I have a piece of foam that used to go on my wristroller before I thickened the handle.
